Other than hot pot, Japanese and western cuisine would be served the fastest. This was because, considering the order of serving and the importance of the ingredient's freshness for the enjoyment of the food, the time spent at these restaurants would be short. The dishes were served separately with a logical order. For example, not long after they made their choice, the first dish, which normally would be soup, would be served. While they enjoyed the soup, they would be waiting for the other dishes until the final dessert or fruit plate was served. The whole process would not take that long.
If this was some other cuisine, things would be different. The chef would prepare all the dishes and send them out all at once. The whole table of food would give the diners enough time to be slow and pick at it. Combining the waiting time and the time used for chatting over meals, basically, a meal would not end until it had gone over one or two hours.
